What is a Lottery?

A lottery is a game of chance in which numbers are drawn for a prize. Modern lotteries are government-run games that involve the purchase of tickets in return for a chance to win a prize, but they may also be privately sponsored and run. Lottery laws differ by country, but many restrict participation to citizens or residents of the state. Those laws are often intended to prevent gambling, which involves paying for a ticket with the intention of winning money. Lottery is not a form of gambling, but some people who buy lottery tickets do so for entertainment value or to fantasize about wealth. These values are not accounted for by decision models that consider expected utility maximization.

In the United States, lotteries have been used to fund public projects and social services. For example, the Continental Congress held a lottery to raise funds for the American Revolution. Benjamin Franklin sponsored an unsuccessful lottery to build cannons to defend Philadelphia against the British, and Thomas Jefferson sought a private lottery to alleviate his crushing debts. Private lotteries have also been used to sell products or land. Despite these uses, critics argue that lottery games are nothing more than a disguised tax on the poor. Numerous studies have found that those with lower incomes play lotteries at proportionally higher rates than do the rich. Furthermore, lottery retailers and suppliers make heavy contributions to political campaigns, making it hard for state politicians to reject lotteries as a source of revenue.
